一种用于高温环境状态的覆铜板
摘要：
本发明公开了一种用于高温环境状态的覆铜板，所述的覆铜板包括玻纤布基层、铜箔层以及树脂，将所述玻纤布基层浸以树脂，单面或双面覆以铜箔层，经热压形成一种板状材料，所述树脂由双酚A型无卤环氧树脂、双酚F型无卤环氧树脂、马来酸酐接枝聚乙烯、含磷环氧树脂、有机硅树脂、聚酰亚胺、丙烯酸树脂以及脲醛树脂组成。本发明能够大大地提高树脂的耐高温性能，使得由玻纤布基层、铜箔层以及树脂制成的覆铜板的耐高温性能得到提高与改善，防止覆铜板在高温环境下产生形变或变形，防止其发生开裂的现象，从而延长其使用寿命。
摘要（英）：

The invention discloses a copper coating plate used in a high temperature environment state. The copper coating plate comprises a glass fabric base layer, a copper foil layer and resin, wherein the glass fabric base layer is immersed with resin, the copper foil layer is coated on a single face or double faces, and a plate material is formed through hot pressing; and the resin is composed of bisphenol A type halogen-free epoxy resin, bisphenol F type halogen-free epoxy resin, maleic anhydride grafted polyethylene, phosphorus-containing epoxy resin, organic silicon resin, polyimide, acrylic resin and urea resin. The copper coating plate disclosed by the invention can greatly improve high temperature resistance of the resin, so that the high temperature resistance of the copper coating plate made from the glass fabric base layer, the copper foil layer and the resin is improved, the copper coating plate is prevented from producing deformation in a high temperature environment, and the phenomenon that the copper coating plate is cracked is prevented, so that the service life of the copper coating plate is prolonged.
